方程（x﹣5）（x+2）=1的解为（　　）

    Now satellites(卫星)are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成). They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
    Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare(比较)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
    So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead(提前).

简单道理

    从前，有两个饥饿的人得到了一位长者的恩赐：一根鱼竿和一篓鲜活硕大的鱼。其中，一个人要了一篓鱼，另一个人要了一根鱼竿，于是，他们分道扬镳了。

得到鱼的人就地用干柴点起篝火煮起了鱼，狼吞虎咽，还没有品出鲜鱼的肉香，转瞬间，连鱼带汤就被他吃了个精光。不久，他便饿死在空空的鱼篓旁。另一个人则提着鱼竿继续忍饥挨饿，一步步艰难的向海边走去。可当他看到不远处那蔚蓝的海洋时，他的最后一点力气也使完了。他也只能眼巴巴的带着无尽的遗憾撒手离开人间。

 有另两个饥饿的人，他们同样得到了长者恩赐的一根鱼竿和一篓鱼。只是他们并没有各奔东西，而是商议共同去寻找大海。他们每次只煮一条鱼。他们经过遥远的跋涉来到海边。从此，两个人开始了捕鱼为生的日子，几年后，他们盖起了房子，有了各自的家庭子女，有了自己建造的渔船，过上了幸福安康的生活。

    一个人只顾眼前的利益，得到的终将是短暂的欢愉；一个人目标高远，但也要面对现实的生活。只有把理想和现实结合起来，才有可能成为一个成功的人。一个简单的道理，却能给人意味深长的启示。
